Application led October 28, 1908. Serial No. 459,835.

.To all whom it may concern:

Be it known that I, ARTHUR VVEsT, a citizen of the United States, residing` at Chicago, in the county of Cook and State of Illinois, have invented certain. new and useful Improvements in Ventilating Systems, of which the following is a specification.

My invention relates to certain new and useful improvements in Ventilating systems for railway cars, and the object thereof is to provide a system which will be simple in con.- struction, not liable to get outof order, capable of being installed in cars now constructed and which will effect the following desirable results: iirst, a constant, even and regulable supply of fresh air and an exhaust of air without danger of draft; second, a perfect supply of pure air from which `all dust and other' impurities have been removed;` third, in cold weather a warmed atmosphere of pure air, and fourth, a supply'of pure air to the upper berths of a sleeping car when the saine are made up.

With these and other objects in view the invention consists-in certain constructions, combinations, and arrangements of parts the preferred form of which will be 'first described in connection with the accompany ing drawings and then the invention particu larly pointed out in the appended claims.

Referring to the drawings wherein the saine part is designated by the same refer ence numeral wherever it occurs Figure i is a diagrammatic view, with parts broken away, partly in section and partly in elevation 5 Fig. 2 is a central section through one of the supply boxes which run beneath each pair of seats, also showing the means for supplying fresh air to the upper berth. Fig. 3 is a detail perspective view of the air intake. Fig. l is a detail sectional view of a iortion of the boxing which runs longitudinallly of the car. Fig. 5 is a central sectional view ofthe means for exhausting the air from the car which is located at the top thereof. Fig. 6 is a front view partly broken away of the berth curtain, showing the means for supplying air to the upper berth, and Fig. 7 is a detail perspective view of the cylinder which forms a portion of the air exhaust device shown in Fig. 5.

The p articular form of construction which I have chosen to illustrate my invention` shows it as particularly adapted for a sleeping car constructlonainl .in the following description I `will particularly describe this form of my invention. It is to be understood however that my invention is not .limited to such use, but that by properly modifying the details my system of ventilation may be used on any forni of carzor in any other relation that may be found desirable.

l designates the outer wall of a car and 2 the inner wall or sheathing between which I locate the boxing 3 which extends the length of the car and preferably at about the height of the licor. rIhe boxing is closed at each end, as shown at 4, and adjacent the ends I cut an opening through the side of the boxing and the outer wall of the car. rlhe upper and lower sides of the boxing at the opening are preferzlflily provided with the triangular. extensions 5 which extend out beyond the outer wall l of the car as shown inFig. 1.

6 is a door hinged at 7 to the edge of each opening, the doors of the two openings each being hinged to the edge of the opening awayfrorn the adjacent end of the car, whereby the door at the front end of the car when the car is ruiming will always be in position to scoop air into the boxing 3. In orderto increase this scooping action I preferably provide thesides of the door with the triangular extensions 8 which are similar' to and lie parallel with the extensions 5.

In the form by which I have illustrated my invention 9 area series of boxings which extend from the inner side of the boxing 3 under the car seats (indicatedv by the dotted lines l0 in Figs. l and 2) to the aisle ofthe car. In a sleeping car construction one of these boxings extends under each pair of seats which are back to bach. each of these boxings are two screens lil-Jil by ineans of which einders and the like carried by the air will be stopped. Preferably I form the end of each boxing 9 into an cnlarged structure 12, closed at its open end by a screen door 13 hingedA to the `box at 14. Between the box and the pipe 9 I inter-pose a screen l5 and :etween the screens 13 and l5 I place a sponge or like filtering medium 1 6. I prefer to use a sponge for this medium, as it may be lnoistened from time to time which not only assists in catching the very fine dust which may be carried by the air, but also prevents the air in the car from becoming too dry. In order to provide a water supply for the sponge I have shown a tank lprovided with a minutely perforated or porous bottom 122, whereby water may seep from the tank onto the sponge.

Located in l lao perforation 46 in which the lower end of the tube is secured. The cover is also provided with a band of perforations l? in line with the absorbent material 411.

In Figs. 2 and 6 I have shown my preferred form of means for Ventilating the upper berths, and, as there shown, consists in providing the ordinary form of berth curtain i8 with a pocket a9 by securing to the inside of the curtain a strip 50 of the same material. In this pocket is secured a pipe 5]. of canvas or similar material which is formed with an elbow at each end which extends through the strip 50. These elbows are so arranged that the lower' one will rest in front ol" a ventilator opening 13 while the upper end is above the mattress of the upper ier-th, as best shown in Fig. 6.

I realize that considerable variation is possible in the details of construction and arrangement of parts without departing from the ispirit of my invention, and I therefore do not intend to limit myselll to the speci'lic form sliown and described.

What I claim as new and desire to secure by Letters Patent is@ 1. A Ventilating system for cars and the like comprising a boxing located in the side oi the car adjacent the iloor line and extending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each end thereof, means for regulating the size of the openings and deliecting air into the boxing, said boxing being also provided with openings extending into the car.

2. A Ventilating system for cars and the like comprising a boxing located in the side of the car and extending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each end thereof, means for regulating the size of the openings and dellecting the air into the boxing, said boxing being also provided with openings extending into the car, the iloor of said boxing inclining from its ends toward the middle, and a pipe extending downwardly from the floor oi' the middle portion.

3. A Ventilating system for cars and the like comprising a boxing located in the side of the car and extending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each end thereof, means for regulating the size of the openings and dei'lecting air into the boxing, said boxing being also provided with openings 'extending into the car and means for regulating the air admitted to the car through said last mentioned openings.

4. A Ventilating system for cars and the like comprising a boxing located. in the side of the car adjacent the iloor line and extending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each end thereof, a scoop adapted to open and close each opening to deileet air into said boxing, said boxing being also provided with openings extending into the car.

5. A Ventilating system for cars and the like comprising a boxing located. in the side of the car and extending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each 4end thereof, a scoop adapted to open and close each opening to de'llect air into said boxe ing, said boxing being also provided with openings extending into the car, doors for regulating the flow of air admitted to the car through said last mentioned openings, and means common to a portieri of the doors and one of the scoops `for operating them.

6. A ventilating system for cars and the like comprising a boxing located in the side oi the car adjacent the floor line and ex tending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each end thereof, means for regulating the size of the open ings and dei'lecting air into the boxing, boxings extending from said longitudinal boxing under the seats ol the car and means located in said boxings tor freeing the air from dust and cinders.

7. A Ventilating system for cars and the like comprising a boxing located in the side oi the car and extending longitudinally thereof, said boxing being provided with an opening extending outside the car adjacent each end thereof, means for regulating the size ol the openings and deliecting air into the boxing, boxings extending from said longitudinal boxing under the seats oi the car, the iloor of said last mentioned boxings being inclined toward the iirst mentioned boxing, and means located in said boxings for freeing the air from dust and cinders.
